This study aims to propose a robust hybrid sliding mode artificial neural network control (SM-ANN) scheme for controlling the stator power (active/reactive) of a doubly fed induction generator (DFIG)-based direct drive vertical axis wind turbine (VAWT) power system under a real-world scenario wind speed that will be installed in the Adrar region (Saharan zone) of Algeria. The SM-ANN scheme will control the stator power of the direct drive VAWT power. The chattering phenomenon is the most significant disadvantage associated with sliding mode control (SMC). In order to find a solution to this issue, the artificial neural network (ANN) method was applied to pick the appealing part of the SMC. MATLAB/Simulink is used to do an evaluation, after which the SM-ANN controller being suggested is compared to both traditional sliding mode (SM) and proportional-integral (PI) controllers. The results of the simulation demonstrated that the recommended SM-ANN controller has good performance in terms of enhancing the quality of energy that is delivered to the power network. This is in comparison to the traditional SM and PI controllers, which both have a long history of use. Notwithstanding the fact that there is DFIG parameter fluctuation present.

With the wide application of clean energy, the requirements of this vertical axis wind turbine are higher and higher. A new diagonal spiral blade vertical axis wind turbine is designed and studied. The shape of the new type of wind turbine blade is designed based on the diagonal spiral structure that is common in life, considering the situation of different pitch angles and constructing 11 kinds of prototype machine. In‐depth analysis of the aerodynamic performance of these new wind turbines through simulation calculations shows that the prototype with a pitch angle of 110° has the best aerodynamic performance. When the tip speed ratio is 0.4, the maximum wind energy utilization rate can reach 0.29. Besides, the model of this wind turbine is constructed by 3D printing, which is tested, and the performance of the models is compared with that of the traditional S‐type wind turbine in a real environment. There rationality and superiority of the design of the new diagonal spiral blade vertical axis wind turbine are proved, and this apply background of this new diagonal spiral blade wind turbine is demonstrated by comparison. This article also analyzes the wake of the wind turbine and makes reasonable planning of the arrangement spacing that the wake effect has the least effect on the downstream wind turbine, which can increase the power generation efficiency of the group arrangement of turbines.

“…In the field of WECS, several studies have been successfully applied to reach the control purposes. For example, in [44], a gain scheduling pitch and MPPT are used in a vertical axis wind turbine. Linear matrix inequalities are solved to design a gain scheduled controller and utilized for the rotor turbine stability control.…”

Mathematical models and algorithms for maximizing power extraction have become an essential topic in renewable energies in the last years, especially in wind energy conversion systems. This study proposes maximum power point tracking using gain scheduling approximations for an emulated wind system in a direct-drive connection. Power extraction is obtained by controlling the duty cycle of a Multilevel Boost Converter, which directly varies the rotational speed of a permanent magnet synchronous generator directly coupled to a three-phase induction motor that emulates the wind turbine. The system’s complexity is linked to the inherent non-linearities associated with the diverse electrical, mechanical, and power electronic elements. In order to present a synthesized model without losing the system dynamic richness, several physical tests were made to obtain parameters for building several mathematical approaches, resulting in non-linear dynamic equations for the controller gains, which are dependant on wind speed. Thirty real operational wind speeds considering typical variations were used in several tests to demonstrate the mathematical models’ performance. Results among these gain scheduling approaches and a typical controller constant gains mathematical model were compared based on standard deviations, absolute error, and the time for reaching the optimum generator angular speed related to every wind speed.
